You don't put the type parameters with the constructor when declaring generics.

You are double-declaring variables, and referencing never-defined variables, has nothing to do with imports. -

I still do not understand why I am getting an error message where I pointed it out, nor can I get the program to find the maximum of the 5 integer values, any thoughts?
That's not what Math.max() does. http://docs.oracle.c.../lang/Math.html look at that to find what it actually does. If you really want to do that, every time they enter a value, if that value is greater then some int variable, set the int variable to that value. -

//This program is to calculate the sum, average, and maximum of 5 numbers. import javax.swing.JOptionPane; public class numberFacts { public static void main (String[] args) { String input; int numbers = 5; int sum = 0; int average = 0; int max = Integer.MIN_VALUE; for(int counter = 0; counter<numbers; counter++) { input = JOptionPane.showInputDialog("Please enter an integer number."); int num = Integer.parseInt(input); sum += num; max = Math.max(max, num); } average = (sum/5); JOptionPane.showMessageDialog(null, "The sum of the numbers is " + sum); JOptionPane.showMessageDialog(null, "The average of the numbers is " + average); JOptionPane.showMessageDialog(null, "The maximum of the numbers is " + max); System.exit(0); } }
I am still getting the "cannot find symbol" error message for line 24, I am confused
Also, is there a way to write this code without using the MIN_VALUE? We have not covered this in class yet. Although I'm sure it would not lose me points, I just don't know its application or understand it, and I'd like to be able to complete the assignment without using parts of code I do not understand.
Uhm, Integer.MIN_VALUE is the field that represents -2^32, and I'm assuming that is not your intention. I think the original poster meant for you to change that, not just copy and paste the code... -
